ME800 MV Industrial Drive

Power range:
- 3kV, 3.3kV: 250kW-2500kW
- 6kV, 6.6kV: 280kW-8000kW
- 10kV, 11kV: 280kW-12500kW
Integrating power electronic technology and vector control technology, perfect harmonic free high voltage source type high voltage drives
Through the phase-shifting rectifier transformer, the input harmonic current at the grid side is greatly suppressed
Voltage superposition is realized by cascading multilevel H-bridge power units, has excellent high-voltage sine wave output and can directly drive high-voltage motor without any filter,The harmonic index meets the requirements of IEC STD 519-1992 (International Electrotechnical Commission) and GB / T 12668.4-2006 (national standard) for grid harmonics

· Multi-level PWM control mode, providing sine wave current output. Low common mode voltage and du/dt, no special requirement for the motor and cable. When upgrading the equipment, it is not necessary to replace the motor.

· Multi-pulse rectifier can effectively suppress higher harmonics and harmonic ratio is far less than the national standard (THD <5%).

ME800 MV Industrial Drive

· Various motor control technologies: drive asynchronous motor and synchronous motor (permanent magnet synchronous and other excitation synchronous)

ME800 MV Industrial Drive

· System components: main control chip of drives integrates the most advanced and mature ARM core processor; the control of each power unit is realized by a large FPGA programming chip; the main control board can directly communicate with the IO board to realize the functions of DI/DO and AI/AO, with fast port response, without PLC.
